ln the embodiment of my invention illustrated in the accompanyingdrawings,-26 indicates the main frame, which is preferably rectangularin form and made of channel-iron. This frame is mounted on front wheels27 and rear wheels 28, the latter beingl of the type usually employed intraction engines so as to provide suflicient traction to insure theproper operation of the niachinery, driven by the rear wheels. ln theconstruction shown7 the rear wheels 28 are i loosely mounted upon a liverear axle 29, having ratchet-wheels '30 adjacent to the hubs of thewheels 23 adapted to be engaged by pawls 31 secured to the wheels, asshown in Figs. 2, il and 6. The purpose of 'this construction is topermit the wheels 28 to turn backward without driving the shaft and topermit the machine to turn readily. Any other suitable construction forthis purpose may be employed. The rear portion of the machine frame 26is mounted upon the rear axle 29 by bolsters 32, shown in Fig. 6. Asshown in Fig. 4f, the rear axle 29 carries two oppositely-disposedbeveled. gears 33-34t which are keyed to said axle so as to rotatetherewith. 35

indicates a beveled pinion which meshes with the beveled gear 33; and 36indicates a beveled pinion which meshes with the beveled gear 3l. rllhepinion 35 is mounted upon a shaft 37' which extends toward the rear ofthe machine, as best shown in F igs. i and 12, its rear end 'beingjournaled in a suitable bearing,i 38 provided in a stirruplike hanger 39which is secured to and depends from a frame el@ which is secured to therear end of the main frame 9.6, preferably at the under side thereof,and extends for a considerable distance rearwardly therefrom, best shownin Fig. 12. rFlic purpose of this rear frame is to support thetransverse elevator and other parts of 'the machine, as will hereinafterappear. 41

indicates a sprocketnvheel loosely mounted upon the rear end portion ofthe shaft 3G and having?,` clutch-member 42 at one side thereof adaptedto be engaged by a clutchmember mounted ena feather on the shaft 3?. soth by moving said clutch-member 37 'the sprocket-wheel 41 may beoperatively connected with. said shaft or may be disconnected therefrom,at pleasure. As shown in Fig. Q, the clutch-member is adapted to beshifted by means of a handlever 4A- located for convenient operation bythe operator of the machine and connected by a connecting-rod Ll with aswinging` arm l-(l, which, at its lower end, has!` a fork adapted toengage a grooved collar i7 which forms a part of the clutch-member 43.The arm 46 is pivoted at its upper end to the fra-me ll-O in anysuitable way, the arrangement beingl such that by operating the lever-llc the clutch-member 43 may be moved toward or from the clutch-membera2, thereby operatively connecting or disconnecting the sprocket-wheel4:1 with the shaft 37. The sprocket-wheel -l-l drives the transverseelevator at the rear of the, machine through certain sprocket-wheels andchains which are `best shown in Figs. a and 6. As there in shown, i8indicates a chain which operates on the sprocket-wheel il and on asprocket-wheel a9 mounted on a short counter-shaft 50 suitably supportedby the frame ell). 'lhus the shaft 50 is driven by the spi'ocketwheela9. The shaft 50 carries a large sprocket-wheel 5l which, as best shownin Fig. 6, drives a chain 5&2 which runs over a small sprocketwheel 53mounted at the upper end of the rear elevator frame 54. T hesprocket-wheel is mounted upon one end of a roller journaled in suitablebea-rings at the upper end of the elevator frame 5a and adjustablelongitudinally thereof by means of screws 56 and nuts 57, as best shownin Fig. (3,-the purpose of this adjustn'ient being" to regulate thetension of the conveyor belt which is driven by said roller. The rearele vatoir comprises an endless belt 5S running over a series of rollerssuitably journaled in the elevator frame 54, the roller being theuppermost one. T he construction of the elevator frai ne is best shownin Fig'. 2l, in which 59 indicates the roller at the lower end of theelevator frame, and G() intermediate rollers which support the belt 58at intervals. 61 indicates rollers carried at the under side of theelevator frame 5st to hold down the upper portion of the chain 52; and(l2-63 indicate rollers carried by a bracket G-il depending` from theelevator frame 54C over which the upper and lower parts of the chain.run. as shown in Fig. G. It will be apparent from the foregoingldescription that 'when the clutch-menlber 43 is in engage'ement with theclutch-mei'uber 42 and the machine advancing, the belt of the transverseelevator will be driven so as to carry material delivered upon the lowerend thereof up and across the rear end of the machine, where it will bedischarged from the upper portion of the belt. As illus trated in Fig.G, the transverse elevator 54 is of such length and is so disposed thatits lower end projects some little distance beyond the left-hand side ofthe machine frame, viewed from the rear, while its upper end projects aneven greater distance beyond the right-hand side of the machine. rThearrangement is such that a wagon may be driven along beside the machine,at the right-hand side thereof, under the upper end of the transverseelevator, so that the material discharged from said elevator will bedeposited in the wagon as the machine advances. lindicates side boardsat the sides of the elevator frame 5l to prevent the material being`carried by the belt 58 from falling' off at the sides thereof.

The shaft 50 is also provided with a sproclietwheel 56 which drives abelt GT operating on small sprocket-wheel 68. The latter sprocket-wheel,as shown in Figs. 6.. "23 and mounted on a shaft 69 disposedtransversely of the elevator 5l, near the lower end thereof. rThe shaft69 is mounted in suitable liiearings in a: box 70 secured at one side ofplate 7l, said plate forming with a parallel plate 72 an open frame, asshown ii 21h-these plates being spaced apart by blocks f3-'74s. Thisframe extends 'transversely ofthe rear elevator belt 5S, and is suitablysiuyported by the elevator frame Between the plates 7 1-72 is mounted anendless belt 75 carrying' scrapers 78 on its oute surface., said beltbeine mounted upon and operated by sprocket-wheels T9- 80, as shown inFito'. :23. The sprocketwheel 79 is mounted on a sha-ft Sl `iournaled inthe side-plates YL-7:2. and the sprocket-wheel 8() is mounted uponasimilar shaft S2. disposed adjacent to the box T0 through which it projects.. and in which is carried a worinovheel S3 which. meshes with aworm SJC carried by the shaft 69., as best shown in F ig. Thus therotation of the sproclret-wheel G8 rotates the worm 84: and through itthe worm-wheel S3 and shaft 82. The rotation of the latter shaft rotatesthe sprocket-wheel 8O and drives the scraper-belt '77. The scrapers 7Scarried by said belt, moving transversely of the inner surface of theelevator belt 58, adjacent to the lower roller 59. as best shown inFig'. 23. remove any dirt or other material accumulatins inside the beltat its lower end, and thereby keep it in proper operative condition. lprefer to strengthen and support the plates 71.#72 by an elonbatedlstrip or block placed within the scraper-belt 77, as shown in Fi n'. Q3,and secured to said plates. 87 indicates a box-like structure whichextends around the lower portion of the elevator frame :3L-t,

88 indicates the elevator frame of the lateral or primary elevator,which is similar 'n neral construction to that of the transve se orsecondary elevator. having' an endless belt S9 supported by rollers insubstantially the saine way. indicates the upper roller of the elevatorbelt 89 which is adjustable in the same way as the corresponding rollerof the secondary elevator. l also prefer to provide a transverse scrapertor the primary elevator, as indicated at `91 in Fig. 2. The primaryelevator frame 88 is disposed outside ot the machine trarne and in theconstruction illustrated is at the letthand side ot the machine andextends 'toreand-att in an inclined position,as shown in Figs. 2 and 4l.lts upper end extends over the lower end of the secondary or transverseelevator to a greater or less extent, as may be necessary to insure thedischarge oi.1 the materials carried up by the primary elevator on tothe secondary elevator belt. As shown in Fig. 6, the upper end ot theprimary elevater trame is carried by a bail 92 suspended by a hook 93from a frame 9dwhich suitably supported by the main frame 26, as shownin Figs. 2, l. and G. 95 indicates a brace 'for the traine 94e. By thisconstruction the primary elevator may be swung; to incline it to thehorizontal to a greater or less extent. and it also may be adjustedlongitrulinally, as may be necessary in the operation ot' the machine.'lfheinanner in which the lower end of the primary elevator is supportedwill be hereinafter described. The primary elevator belt is driven 'fromthe rear axle 29 through the beveled gear S-l and pinion The .latterpinion is mounted upon ai shaft 90, shown in Fig. el, which can ries abeveled pinion 97 meshing with a similar pinion 9S mounted on a shatt 99journaled in suitable bearings supported by the main traine 20.preferably by liano'ers 100-101-102, as shown in Fig. 12,-tnes hangersbeing connected by longitudinal and cross-bars to form a substantialtrame, as illustrated in Figs. @L and 12. rEhe sha'lt 99 carries aclutch-member 103 which is mounted on a feather thereon so as to rotatetherewith, said clutch-member beingv adjustable by a lever 104, shown inFigs. 2 and 1. The clutch-member 10.8 is adapted to cooperate with aclutch-member 105 car* ried by a sprocket-wheel 106 loosely mounted onthe shaft 99, so that by causing; the clutchmember 103 to engage theclutch-member 105, the sprocket-wheel 100 may be caused to rotate withthe shaft 99. The sprocket'- wheel 100 is connected by a chain 107 witha spi'ocket-.vheel 10S mounted on a countersha't 109, best shown inFigs. /l and 12, the latter shalt carryii'ig` a sprocket-wheel 110 overwhich runs a chain 111 which also runs on siliirocket-wheel 112 which isconnectedwith the upper roller 90- ot the primary elevator. show n inFig. t, this upper roller is provided with an extension 90" at one endwhich carries the sprocketwheel 112. Thus the roller 90 is driven fromthe rear axle 29 when the latter ro- Lseaeve tates in forward direction.113 indicates :t swinging arm carrying a roller lleiover which the chain111 runs, as shown in Fig. L), said arm 113 being counterbalanced by aweight 115 carried by an arm 110 connected to the pivot 117 the arm 113,as shown in said ligure. The weight 115 thereby holds the chain 111comparatively taut. As shown in Figs. 2 and il, the shaft 109 extendsthrough the sprocket-wheel 110 and carries another sprocket-wheel 11Sover which operates a chain 119 which drives the transverse scraper torthe primary elevator, in the saine manner as the scraper for the upperor secondary elevator is driven.

rEhe trent end of the primary elevator is pivotally supported by straps120121 which depend from the side bars 122-123 of a traine arranged atthe lett-hand side of the machine, as shown in Figs. 3 and 10, the lowerroller 902L of said elevator being ournaled in said straps, as shown inFigs. 10 and 13. The members 122123 are proffen ably channel-bars andtheir ends converge and are secured to the intermediate portion of an-beam 121-, and ',lhe members 12E-L3 are connected at the rear bv across-bar 125, as shown in Fig. l and 'one frame comprising the sidemeinb r" 122 12B is suspended from the main traine ot the machine andheld in position in the manner shown in Fig. 10. As therein shown. thecross-bar 125 is connected centrally by a pivot 126 with-the outer endot a control bar 127, the opposite end oit which is connected by a pivot128 with a yoke and this yoke is connected by a pivot- 130 with abracket 131 depending trom one ol the side bars of the main traine 20,as best shown in Figs. 10 and 11. The pivot 12 yoke 129 and pivot 130are arranged. to form a universal joint, so that the control bar 127 mayturn axially about the pivot 130 or swing about the pivot 12S, thuspermitting` the elevator frame to be adjusted freely within reasonablelimits. Also, by pivoting the bar 125 to the bar 127, the elevator.traine 88 is permitted to rock to tilt it about its longitudinal axisand change its angular position with relation to a horizontal plane. Thepurpose of this adjustment will be hereinafter set forth. The bar 127 isnormally in substantially a horizontal position, although it may beswung up or down troni such position. lt is supported by a rack-bar 132,the toothed portion 13? ot which eiivigges a pinion 1341 mounted on ashaft which also carries a gear 130, as shown in Fi 10. These parts aremounted in a traine 187 carried by supports 13S-139 rising from one ofthe side bars ot' the main traine 20, as best shown in Figs. 2 and 10.'lf he raclebar 1.32 is held in n'lesh with the pinion 184 by anidler-wheel 1l0, as shown in Fig. 2. rlihe gear 130 meshes with a pinasbest shown in Figs.

the lower end of which is connected to the rear inner portion of thescoop, while its upper end is connected by a pivot 17d to the member122, as shown in 7. rllhe brace 173 is itself braced intermediately by abrace 175, the upper end of which is connected by a break-pin 17 6 withthe member 122. Thus the brace 173 may swing backward to allow the scoopto yield under extraordinary strain which might damage it if it could Asbest shown in F 1, the bottom of the scoop 157 is set at quite apronounced angle to the grounc. so that it enters the ,around readily,and the materials excavated are caused to move back over the uppersurface of the scoop to the primary elevator upon the lower end of whichthey are automatically deposited, being then immediately carried up bysaid elevator and deposited on the secondary or transverse elevator,which carries them across the machine and deposits them in the wagonplaced In order to break up extremely hard material, such as macadamizedroad-beds or packed gravel, or to meet conditions where the difficultiesof )lowing` are unusually great, 1 provide a rooter 1.77, which, in theconstruction shown in 1, is in the form of a heavy pointed share havinga shank 178 by which is secured The shank 178 is bent -at such an anglethat it r)ccupies a horizontal position when the share is in operativeposition, and is supported by brackets 179-180 attached to the underside of the beam 1241-, said brackets being` slotted to receive theshank 17 8. A cross-key 181 passed through the forward end of the beamin front of the bracket 179 and a. pin 182 passed through the shank atthe rear side of the bracket 180, hold the rooter in operative position.1t may, however, be readily removed by removi g the key 181. The shank178 shaped to fit the slots in the brackets 179-180, which arenon-circular, so that the rooter is held against lateral swinging. Thisrooter is disposed in front of the scoop 167 so that it breaks up theground in advance of the scoop. In 13 1 have shown a modifiedarrangementof rooter, comprising a straight bar 183 pointed at its lowerend, said bar being supported by a collar 183 connected by a break-pin18st with a bar 185 connected by a pivot 186 with a bracket 187 securesat the under side of the ii-beam 124; also by a collar 188 pivoted upona cross-bar 189 which is supported by the members 122-- 123, as shown inFig. 1st. A. bolt 190 passing` through the bracket 1.88 and bar 183holds the bar 183 against endwise movement. In case the rooter meetswith a relatively immovable obstacle, the pin 18% may break or besheared off, which will permit the point of the rooter to swingbackward.

This form of rooter is also removable by removing the pin 190.

In operation the rear end of the beam 124 and the side members 122 123are lowered to the depth at which it is desired to have the excavatingdevices operate by means of the rack-bar 132. The rooter will then cutinto the ground and the materials loosened by it, as well as othermaterial, will be scraped up by the scoop and deposited upon theelevator 89, by which it will be carried up and delivered ashereinbefore described.

The draft devices are best shown in Figs. 1, 3, 15 and 16. fis thereinshown, the front axle 191 carries the usual .fifth wheel 192 on whichthe front part of the frame 26 is supported by bolsters 193, as shown inFig. 1. A king-bolt 1911 is provided, as usual, but it is extendedupward above the main frame 26 and at its upper end is provided with aswiveled upright loop 195, shown in 19. rllhe upper portion of thekingbolt is braced by braces 196, as shown in Figs. 1 and 3. Secured tothe lower member of the fifth wheel 1.92 is a draft-frame comprisingside bars 197, cross-braces 198, and two parallel transverse bars 199secured to the side bars 197 intermediately of the length thereof. Theforward ends of said side bars converge and are secured at opposite endsof a short horizontal f-beam 200, as best shown in Figs. 17 and 18. 201indicates a tongue, which is preferably a channel beam, and has at itsrear end a segmental rack 202, as best shown in Fig. 15. This Vrackoperates between the two crossbars 199, as shown in Figs. 16 and 17. 203indicates a worm-wheel shaft, which is supported in a vertical positionby the bars 199, midway of the length thereof, and, carries a pinion20st which meshes with the teeth of the ck 202, it its upper end thewormwheel shaft 203 carries a worm-wheel 205, shown in Fi 1 and 5, withwhich meshes a worin 205 carried by a worm shaft 207 having a fork 208at its rear end, as shown in it.. This worm shaft is mounted in a.suitable bracket 209 held in position by a brace 210, as best shown inFigs. 1 and The rear end of the brace 210 is connected to a crossebar211 secured to the side bars 197. The fork 208 forms part of a universalcoupling` 212 with which connects a steering shaft 213 which extendsback through the slot in the loop 195, as shown in Fig. 1, and carriesat its upper end a steering wheel 2 Thus the steering shaft 213 issupported by the king-bolt, but owing` to the swiveling of the loop 195and the fact that the axis of said loop alines with the axis of theking-bolt, the turning of the front axle in steering is not interferedwith. The tongue 201 is pivotally connected with the beam 200 by a pivot21.5, as best shown in Figs` 1o and 18, said pivot passing through thebeam 20() and through a U-shaped crossbar 216 secured to the beam 200.21'? indicates an anti-friction Washer between the tongue 201 and thebea-1n 200. '218 indicates a longitudinal truss for the tongue, as shownin 17, said truss having a strut The truss L18 is also preferably achannel bar, as shown in Fin'. 1S. Bv rotating' the steering' wheel21g-l, it ivill be apparent that the worm shaft 203 mayv be rotated,ther-cb;7 swinging the tongue 201 to one side or the other about itspivot and changing' its angular relation to the longitudinal axis ot themachine, thus enabling the operator to cause the machine to run off toone side or the other. as may be desired in its operation. i220indicates a chain for supporting the outer end portion ot the tongue,said chain being` preferablv connected to the tongue by a loop 221 whichembraces the truss 218 and bears against the strut '219, as shoivn inFifa'. 17. The rear end et the chain 220 is vieldinglv connected bv aspring' with a ring 223 fitted upon the lower end portion ot the loop195, as shown in Fig. 1. 252-1 indicates a chain, the torward end ofwhich is connected to the king-bolt 19-'1- immediateltY above the fifthWheel 19.2. its rear end being connected to the control bar 151, asshown in 1. indicates another chain, Which may be a part ot the chainand which extendsback Ytrom the control bar 151 to the bar 100. as shownin 'Fig'. 9,. The chain operates` to pre'l'ent thei control bar 151 fromswinging baciwhen the excavating' devices are in operation, and thecha-in prevents the side elevator from swinging forward under the actionoit gravity.

From the 'foregoing description it will he understood that with mvimproved machine it is practicable to operate in comparativelv narrowstreets. cuts.` etc.. and that the work ot digging' up or excavating theground mav be very efficiently carried on, as the material taken up bythe excavati devices is at once carried up and across the machine anddelivered to the Wagon placed to receive it. as soon as one wagon isloaded another mav be driven to loading position` and the Work thuscarried on verjv rapidly. The excavating; devices maa'v be raised andlowered to regulate the depth ot the cut. and the scoop may also betilted so as to runV its point into the ground in beginning' a cut ortren. lVhen this is done, the elevator is adjusted correspondintlv. sothat the loadine; oi the eicavatt-a'l. dirt is not interfered with. livconstructing the scoop as sliovvn. vvith one side open. there is nodanger ot choking' it; and b v slantine' it oinavardlv at its torv-ardedge. the bank is always tar enough aavav Ytrom the elevator iframe sothat it does not interfere v'ith it. li it desired to encavate to oneside et the path oi the team or tract-or by which the machine is drawn,this' may be accomplished by turning the tongue at an angle to the trameof the machine by means of the steering Wheel in the manner hereinbetoredescribed. There is no danger ot' clogging the elevators because theScrapers provided Within the elevator belts or aprons near the lowerrollers Which support thenn' continuonslj, clear out any dirt whichfinds its n'ajv inside the belts.
